Qorvo Inc of Greensboro, NC and Hillsboro, OR, USA (which provides core technologies and RF solutions for mobile, infrastructure and aerospace/defense applications) has expanded its portfolio of Wi-Fi products to include new front-end modules (FEMs) designed for wireless broadband home gateways and set-top-boxes.

Offering what is claimed to be the industry's best power consumption, linearity, and throughput, the RFFM4552 and RFFM4558 5GHz 802.11ac FEMs support multi-user multi-input/multi-output (MU-MIMO) with up to 8x8 antenna configurations, allowing gateways to deliver multiple wireless streams simultaneously to different devices, including new 4K ultra-high-definition (UHD) televisions and DVD players. Additionally, the 1024 QAM modulation capabilities enable what are claimed to be the highest data rates possible in Wi-Fi solutions.

"Qorvo's new high-performance FEMs enable service providers and OEMs to differentiate their Wi-Fi routers, broadband gateways and set-top-boxes with improved overall system performance and industry-leading power consumption," claims James Klein, president of Qorvo's Infrastructure and Defense Products. "By offering the best efficiency and thermal performance, our front-end modules help Wi-Fi device manufacturers support the high data rates and throughput needed for today's increasingly connected home," he adds.

The front-end modules deliver system-level compliance in the band-edge to meet FCC regulations and significant performance requirements related to radiated harmonics. The RFFM4552 is available in a 3mm x 3mm QFN package and the RFFM4558 is available in a 2.5mm x 2.5mm package, and both FEMs are sampling now.
